If a picture is worth a thousand words, a picture with a word stamped in big fat letters on it must be worth at least a thousand and one.

With this in mind, we offer Stamp-O-Matic. The only app for the iPhone and iPod Touch that lets you create a big rubber stamp with whatever text you want (custom stamps in full version; free version includes several premade stamps), using a choice of several stamp styles and a bunch of different colors, and slap that stamp onto a picture.

Stamp-O-Matic lets you use any photo in your camera roll, or take a new picture right there in the app. When you're done, pick a stamp (the full version lets you create your own stamp), position it, and then WHAM! Your new stamped picture is ready to go, and you can save it, email it or tweet it right away.
